BACKGROUND

In a 5th-Generation (5G) system, Physical Uplink Control Channels(PUCCHs) of two lengths are supported, i.e., long PUCCHs and shortPUCCHs. A terminal device may send different uplink information by useof different PUCCHs, for example, sending a Scheduling Request (SR) andfeedback information (Acknowledgement (ACK) or Negative ACK (NACK))through different PUCCHs. In such a case, how to transmit the SR and thefeedback information more effectively becomes a problem urgent to besolved.

SUMMARY

In a possible implementation mode, the control signaling may includeDownlink Control Information (DCI) or high-layer signaling.

In a possible implementation mode, the DCI may be configured to scheduledynamic Physical Downlink Shared Channel (PDSCH) transmission, or may beconfigured to activate semi-persistent PDSCH transmission, or mayindicate semi-persistent resource release, or may be configured toindicate Bandwidth Part (BWP) activa ti onideacti vation, or may beconfigured to indicate carrier activation/deactivation.

FIG. 1 illustrates a wireless communication system 100 to which theembodiments of the application are applied. The wireless communicationsystem 100 may include a network device 110. The network device 110 maybe a device communicating with a terminal device. The network device 110may provide communication coverage for a specific geographical regionand may communicate with a terminal device (for example, User Equipment(UE)) in the coverage. Optionally, the network device 110 may be a BaseTransceiver Station (BTS) in a GSM or a CDMA system, or may also be aNodeB (NB) in a WCDMA system, or may be an Evolutional Node B (eNB oreNodeB) in an LTE system or a wireless controller in a Cloud RadioAccess Network (CRAN). Or the network device may be a relay station, anaccess point, a vehicle-mounted device, a wearable device, anetwork-side device in a future 5G network, a network device in a futureevolved Public Land Mobile Network (PLMN) or the like.

The wireless communication system 100 further includes at least oneterminal device 120 within the coverage of the network device 110. Theterminal devices 120 may he mobile or fixed. Optionally, the terminaldevice 120 may be an access terminal UE, a subscriber station, a userstation, a mobile radio station, a mobile station, a remote station, aremote terminal, a mobile device, a user terminal, a terminal, awireless communication device, a user agent or a user device. The accessterminal may be a cell phone, a cordless phone, a Session InitiationProtocol (SIP) phone, a Wireless Local Loop (WLL) station, a PersonalDigital Assistant (PDA), a handheld device with a wireless communicationfunction, a computing device, other processing devices connected to awireless modem, a vehicle-mounted device, a wearable device, a terminaldevice in a future 5G network, a terminal device in a future evolvedPLMN or the like.

Optionally, the terminal devices 120 may perform Device to Device (D2D)communication.

Optionally, the 5G system or network may also be called a New Radio (NR)system or network.

A network device and two terminal devices are exemplarily shown inFIG. 1. Optionally, the wireless communication system 100 may includemultiple network devices and other number of terminal devices may beincluded in coverage of each network device. There are no limits madethereto in the embodiments of the application.

Optionally, the wireless communication system 100 may further includeother network entities such as a network controller and a mobilitymanagement entity. There are no limits made thereto in the embodimentsof the application.

In an NR system, PUCCHs of two lengths are supported, i.e., long PUCCHsand short PUCCHs. Optionally, a short PUCCH includes 1˜2 time-domainsymbols, and a long PUCCH includes 4˜14 time-domain symbols. A terminaldevice may send different information by use of different PUCCHs, forexample, sending a SR and feedback information (ACK/NACK) throughdifferent PUCCHs.

An uplink control channel parameter used for transmission of an SR isusually semi-persistently configured (for example, a configurationperiod, an offset and a PUCCH resource). When a terminal device has anSR, a PUCCH configured to bear the SR is transmitted on a correspondingresource; and when the terminal device has no SR, no information is senton the corresponding resource. A transmission period of an SR (at leastfor an SR transmitted by a short PUCCH) may at least be equal to Xtime-domain symbols, and a value of X may be, for example, 1. Forexample, the SR may be configured to be transmitted by a long PUCCH (forexample, PITCH format 1), and the ACK/NACK may be configured to betransmitted by a short PUCCH (PUCCH format 2).

If there is a conflict between transmission of an SR and transmission ofan ACK/NACK on a time domain, how to send the SR and the ACK/NACKbecomes a problem urgent to be solved.

In the embodiments of the application, a terminal device determines howto effectively transmit information related to control signaling andother information on the basis of time when downlink control signalingis received, so that different information may still be effectivelytransmitted under the situation that PUCCHs of two different lenethsexist

FIG. 2 is an interaction flowchart of a method for informationtransmission according to an embodiment of the application. A networkdevice shown in FIG. 2 may be, for example, the network device 110 shownin FIG. 1, and a terminal device shown in FIG. 2 may be, for example,the terminal device 120 shown in FIG. 1. As shown in FIG. 2, thecommunication method includes the following steps.

in 210, the network device sends control signaling to the terminaldevice at a first time position.

In 220, the terminal device receives the control signaling sent by thenetwork device at the first time position.

Optionally, the control signaling includes DCI or high-layer signaling.For example, the control signaling may be a Physical Downlink ControlChannel (PDCCH). The control signaling may be configured to scheduledynamic PDSCH transmission, or may be configured to activate asemi-persistently transmitted PDSCH, or may be configured to indicatethe release of a Semi-Persistent Scheduling (SPS) resource, or may beconfigured to indicate activation or deactivation of a BWP, or may beconfigured to indicate activation or deactivation of a carrier and thelike.

In 230, the terminal device sends first information and/or secondinformation related to the control signaling to the network deviceaccording to the first time position.

Here, a second time position for sending the first information is atleast partially overlapped with a third time position for sending thesecond information.

Optionally, the first information is SR information or periodic channelstate information.

Optionally, the second information is feedback information, uplink dataor aperiodic channel state information.

It is to be understood that the second information is informationcorresponding to the control signaling, that is, the second informationis related to the control signaling. For example, the second informationmay be information scheduled by the control signaling, informationtriggered by the control signaling, feedback information to the controlsignaling, or the like.

For example, the second information may be the uplink data scheduled bythe control signaling; or the second information may be the aperiodicchannel state information (for example, aperiodically transmittedChannel State Information Reference Signal (CSI-RS)) triggered by thecontrol signaling; or the second information may be the feedbackinformation (for example, an ACK or a NACK) to the control signaling,and is configured to give a feedback to the control signaling.

The first information is information unrelated to the control signaling,and the first information is sent independently of the controlsignaling, and is not information scheduled on the basis of the controlsignaling or sent for the control signaling. For example, the firstinformation may be an SR; or the first information may be periodicchannel state information (for example, periodically transmitted CSI-RS,here, a transmission period of the CSI-RS may be set for the terminaldevice by a network in advance); or the first information may be otherinformation not scheduled on the basis of the control signaling.

If the second time position is at least partially overlapped with thethird time position, the terminal device determines a sending manner forthe first information and the second information according to the firsttime position where the control signaling is received. The secondinformation is information related to the control signaling. Forexample, the second information is the feedback information to thecontrol signaling or information scheduled by the control signaling.

Optionally, the second time position is a time position pre-set or setby the network device to transmit the first information. For example,the network device may set a transmission period, offset, PUCCH resourceand the like of the first information. It can be understood that thesecond time position is a time position originally to be adopted fortransmission of the first information but a factor of the first timeposition is also required to be considered to determine whether tofinally transmit the first information at the time position or not.

Optionally, the third time position is a time position pre-set or set bythe network device to transmit the second information. For example, thenetwork device may contain information of the third time position intothe control signaling for indication to the terminal device. It can beunderstood that the third time position is a time position originally tobe adopted for transmission of the second information but the factor ofthe first time position is also required to be considered to determinewhether to finally transmit the second information at the time positionor not.

If the second time position is at least partially overlapped with thethird time position, then the terminal device determines whether to sendthe first information and/or the second information or not anddetermines a time or channel resource for sending the first informationand/or the second information according to the first time position wherethe control signaling is received; and if the second time position isnot overlapped with the third time position, then the terminal devicemay send the first information at the second time position and send thesecond information related to the control signaling at the third timeposition.

In 240, the network device receives, from the terminal device accordingto the first time position, the first information and/or secondinformation related to the control signaling.

Here, the second time position for sending the first information is atleast partially overlapped with the third time position for sending thesecond information.

If the second time position is at least partially overlapped with thethird time position, the network device may determine whether to receivethe first information and/or the second information or not and determinea time or channel resource for receiving the first information and/orthe second information according to the first time position where thecontrol signaling is received. If the second time position is notoverlapped with the third time position, the network device may receivethe first information at the second time position and receive the secondinformation related to the control signaling at the third time position.

In such a manner, the terminal device determines how to effectivelytransmit the information related to the control sinnaling and otherinformation on the basis of time when the downlink control signaling isreceived, so that different information may still be effectivelytransmitted under the situation that PUCCHs of two different lengthsexist.

There exist two situations in the embodiments of the application. One isthat the first time position is before the second time position, andanother is the first time position is after the second time position.Transmission of the first information and the second information underthe two situations will be described below respectively.

A First Situation

Optionally, in 230, if the first time position is before the second timeposition, then the terminal device sends the second information and thefirst information in a multiplexing transmission manner.

Correspondingly, when the first time position is before the second timeposition, the network device receives the second information and thefirst information which are sent by the terminal device in themultiplexing transmission manner.

Optionally, the situation that the first time position is before thesecond time position includes that: a last time-domain symbol of atleast one time-domain symbol at the first time position is before afirst time-domain symbol of at least one time-domain symbol at thesecond time position.

Optionally, the multiplexing transmission manner refers to packing thesecond information and the first information for transmission together.For example, the second information and the first information aretransmitted by use of the same control channel.

Optionally, the operation that the terminal device sends the secondinformation and the first information in the multiplexing transmissionmanner includes that: the terminal device may send the secondinformation and the first information in the multiplexing transmissionmanner at the third time position. Correspondingly, the network devicereceives at the third time position the second information and the firstinformation which are sent by the terminal device in the multiplexingtransmission manner.

Optionally, the operation that the terminal device sends the secondinformation and the first information in the multiplexing transmissionmanner includes that: the terminal device sends the second informationand the first information through a PUCCH configured to transmit thesecond information. Correspondingly, the network device receives thesecond information and the first information which are sent by theterminal device through the PUCCH configured to transmit the secondinformation.

Optionally, the operation that the terminal device sends the secondinformation and the first information in the multiplexing transmissionmanner includes that: the terminal device sends the second informationand the first information through a PUCCH indicated by the controlsignaling. Correspondingly, the network device receives the secondinformation and the first information which are sent by the terminaldevice through the PUCCH indicated by the control signaling.

For example, as shown in FIG. 3A to FIG. 3C, there is made such ahypothesis that the first information is an SR and the secondinformation is feedback information to control signaling. The terminaldevice receives the control signaling sent by the network device at thefirst time position, and the control signaling indicates the terminaldevice to send the feedback information responding to the controlsignaling at the third time position. Herein, a PUCCH configured totransmit the feedback information may be a short PUCCH (PUCCH format 2).The second time position determined by the terminal device according toa configuration and configured to transmit the SR is after the firsttime position (that is, the first time position is before the secondtime position). Herein, a PUCCH configured to transmit the SR may he along PUCCH (PUCCH format 1). It can be seen that, since the second timeposition is at least partially overlapped with the third time positionand the first time position where the terminal device receives thecontrol signaling sent by the network device is before the second timeposition, it is not suitable for the terminal device to send the SR atthe first time position by use of the long PUCCH, and instead, the SRand the feedback information are transmitted together by use of theshort PUCCH configured to transmit the feedback information at the thirdtime position.

A Second Situation

Optionally, in 230, if the first time position is after the second timeposition and the first information is positive, then the terminal deviceat least sends the first information; and if the first time position isafter the second time position and the first information is negative,then the terminal device only sends the second information.

Correspondingly, when the first time position is after the second timeposition and the first information is positive, the network device mayat least receive the first information sent by the terminal device; andwhen the first time position is after the second time position and thefirst information is negative, the network device may only receive thesecond information sent by the terminal device.

Optionally, the situation that the first time position is after thesecond time position includes that: the last time-domain symbol in atleast one time-domain sythbol at the first time position is after thefirst time-domain symbol of at least one time-domain symbol at thesecond time position; or, the last time-domain symbol of the at leastone time-domain symbol at the first time position and the firsttime-domain symbol of the at least one time-domain symbol at the secondtime position are the same time-domain symbol.

Optionally, the first information being positive represents that thereis the first information, and the first information being negativerepresents that there is no first information.

Optionally, the operation that the terminal device at least sends thefirst information if the first time position is after the second timeposition and the first information is positive includes that: if theterminal device does not support simultaneous transmission of multiplePUCCHs, then the terminal device only sends the first information; or,if the terminal device supports simultaneous transmission of themultiple PUCCHs, then the terminal device sends the first informationand the second information through two independent PUCCHS respectively.

Correspondingly, under the situation that the first time position isafter the second time position and the first information is positive, ifthe terminal device does not support simultaneous transmission of themultiple PUCCHs, then the network device may only receive the firstinformation from the terminal device, and if the terminal devicesupports simultaneous transmission of the multiple PUCCHs, then thenetwork device may not only receive the first information sent by theterminal device but also receive the second information sent by theterminal device. Herein, the first information and the secondinformation are sent by the terminal device through two independentPUCCHs respectively.

Optionally, the transmit power of the first information on alltime-domain symbols occupied by the PUCCH configured to send the firstinformation is the same.

Optionally, the first information is information transmitted through along PUCCH, and the second information is information transmittedthrough a short PUCCH; or, the first information is informationtransmitted through a short PUCCH, and the second information isinformation transmitted through a long PUCCH.

For example, as shown in FIG. 4A and FIG. 4B, there is made such ahypothesis that the first information is SR and the second informationis feedback information to the control signaling. The terminal devicereceives the control signaling sent by the network device at the firsttime position, and the control signaling indicates the terminal deviceto send the feedback information responding to the control signaling atthe third time position. Herein, the PUCCH configured to transmit thefeedback information may be a short PUCCH (PUCCH format 2). The secondtime position determined bye the terminal device according to aconfiguration and configured to transmit the SR is before the first timeposition (that is, the first time position is after the second timeposition). Herein, the PUCCH configured to transmit the SR may be a longPUCCH (PUCCH format 1). It can be seen that, since the second timeposition is at least partially overlapped with the third time positionand the first time position where the terminal device receives thecontrol signaling sent by the network device is after the second timeposition, when the SR is positive (that is, there is an SR), theterminal device is required to send the SR by use of a long PUCCH. Atime-domain spread spectrum technology is adopted for a long PUCCH and,if transmission of the SR is terminated in advance in such a case,orthogonality may be damaged, and thus transmission of the SR should becontinued.

Furthermore, if the terminal device supports simultaneous transmissionof multiple PUCCHs, then the terminal device may send the feedbackinformation by use of a short PUCCH, and if the terminal device does notsupport simultaneous transmission of multiple PUCCHS, then the feedbackinformation is discarded.

When the SR is negative (there is no SR), the terminal device only sendsthe feedback information (ACK/NACK) by use of the short PUCCH.

FIG. 5 is a schematic block diagram of a terminal device 500 accordingto an embodiment of the application. As shown in FIG. 5, the terminaldevice 500 includes a receiving unit 510 and a sending unit 520.

The receiving unit 510 is configured to receive control signaling from anetwork device at a first time position.

The sending unit 520 is configured to send first information and/orsecond information related to the control signaling to the networkdevice according to the first time position where the receiving unitreceives the control signaling.

A second time position for sending the first information is at leastpartially overlapped with a third time position for sending the secondinformation.

In such a manner, the terminal device determines how to effectivelytransmit the information related to the control signaling and otherinformation on the basis of time when the downlink control signaling isreceived, so that different information may still be effectivelytransmitted under the situation that PUCCHs of two different lengthsexist.

Optionally, the first information is an SR or periodic channel stateinformation.

Optionally, the second information is feedback information, uplink dataor aperiodic channel state information.

Optionally, the sending unit 520 is specifically configured to, if thefirst time position is before the second time position, send the secondinformation and the first information in a multiplexing transmissionmanner.

Optionally, the sending unit 520 is specifically configured to send thesecond information and the first information in the multiplexingtransmission manner at the third time position.

Optionally, the sending unit 520 is specifically configured to send thesecond information and the first information through a PUCCH configuredto transmit the second information.

Optionally, the sending unit 520 is specifically configured to send thesecond information and the first information through a PUCCH indicatedby the control signaling.
